(c) Precisely specify the conditions under which the following algorithm returns true, and then discuss, in detail, the running time of the algorithm. If you think it has different best- and worst-case running times then these should be considered separately, and you should explain the conditions under which best- and worst-cases arise. You must fully explain your answer and use 0, 2 and appropriately to receive full marks. Algorithm Ex3 ((aj, ... an), b) 9+0 W = false for i=1 to n - 1 do zai + Qi+1 If z
